TeraBox download interrupted? Check these causes and fixes
The download bar stalls halfway, the button turns grey, and the file never reaches the folder.
Each restart costs another wait, and a file that refuses to resume hides whether the owner deleted it, the source timed out, or a password stands in the way.
Tested 27 September 2026 115 share links By TeraSaver With Love
Short answer. When a TeraBox download stops, the fault is at the source, not your browser. A partial zip will not open until it completes. Of 115 links tested, 94.2% opened. Failures come from deleted files, password locks, no file behind the code, source timeouts, rate limits, or a share refusing access. A 403 means the share refuses access, a 429 clears itself, a 504 is a source timeout. Password-protected or deleted shares cannot be opened.
What you need first
- The share link is correct and has not been deleted by its owner.
- You have the owner-set password for locked shares.
- Your internet connection is stable enough to hold a large transfer.
- You have enough free space on your device for the full file.
Step by step
Identify the error code
When a download stops, the page shows a code such as SHARE_DELETED, PASSWORD_REQUIRED, RATE_LIMITED or UPSTREAM_TIMEOUT. The code determines the fix. Do not retry blindly; read the exact message and match it to the steps below.
Enter the share password
If the code is PASSWORD_REQUIRED, the share is locked by its owner. Enter the password you were given. Without it, no tool can open the share. Retrying without the password will always fail, so only proceed if you have it.
Ask owner to re-share deleted file
SHARE_DELETED means the owner removed the file at the source. No tool can recover it. The only fix is to contact the owner and ask them to share the file again. Do not waste time retrying; the share is gone permanently.
Wait for rate limit to clear
RATE_LIMITED, or HTTP 429, means too many requests were sent in a short time. This clears on its own after a short wait. Pause for a while and then retry. If you use a download manager, it may resume automatically because the CDN supports range requests.
Retry after an upstream timeout
UPSTREAM_TIMEOUT, or HTTP 504, means the source did not answer in time. This has nothing to do with your connection speed. Wait a moment and start the download again. Range requests are supported, so a resumable download manager can continue from the stopped point.
Verify link for 403 errors
A 403 error means the share itself refuses access, not that the link was typed wrongly. Check the share code for a leading 1 that is not part of the code. Try one of the eight supported domains, such as terabox.com or terasharefile.com, before giving up.

Why this works
Opening a TeraBox share through TeraSaver does not route the file through our server. The final download address comes from the source CDN, so the bytes travel straight from TeraBox to your device. TeraSaver only reads the share's file metadata, which is publicly readable without signing in, and hands you the direct link. That direct address answers range requests, so your browser or download manager can resume a stalled transfer rather than starting over. Because the code in a share link can appear under any of eight hostnames and sometimes includes a leading 1 that is not part of the code, TeraSaver normalises those variants to reach the same underlying file. Interruptions usually come from the source: a 403 means the share refuses access, a 429 is a rate limit that clears on its own, and a 504 means the source timed out, none of which reflect your own connection speed. That is why a retry often works after a short wait.
How these figures are produced: our testing method.
When it does not work
This link is password protected.
The share is locked with a password set by its owner (error code PASSWORD_REQUIRED).
Nobody can open it without that password. Ask the owner for the password, or ask them to remove the lock. No tool can get around it.
This file has been deleted at the source.
The owner deleted the file, so the share no longer points to anything (error code SHARE_DELETED).
Nothing can recover the file. Contact the owner and ask them to re-share it.
Too many requests. Please try again shortly.
The source is rate limiting you (error code RATE_LIMITED, HTTP 429). This clears on its own after a short wait.
Wait a little while without sending more requests, then try the link again.
The source took too long to respond.
The source did not answer in time (error code UPSTREAM_TIMEOUT, HTTP 504). This is unrelated to the speed of your own connection.
Wait and retry later. If it keeps happening, the source server itself is having trouble and no client-side change will help.
The download stops partway through a file.
The connection dropped, but the final CDN address answers range requests.
Use a download manager that supports resuming. It can request the remaining part of the file and continue where it stopped.
Limits worth knowing
- A password-protected share cannot be opened without the password, and no tool can bypass that.
- A share whose file was deleted by the owner is gone for good; no tool can bring it back.
- The file is served directly from the source CDN and never passes through TeraSaver, so download speed depends entirely on the source and your connection.
- For a file that keeps interrupting, the better answer is a download manager that supports range requests; TeraSaver cannot force the source to keep a connection alive.
Safety, privacy and rights
We can see the share code and the file list it returns, nothing else. No TeraBox credentials are ever entered, so no login details to store. The file does not pass through TeraSaver; the download is direct between TeraBox's CDN and your device. We keep no copy. If a share returns PASSWORD_REQUIRED, it is locked by its owner, and nobody can open it without that password. No tool or retry changes that. If the owner deleted the file, the share is gone. Your responsibility is to use the tool only for shares you are allowed to access.
Questions people ask
can i use a download manager to resume TeraBox downloads?
Yes. The source CDN answers range requests, so a download manager can pick up where an interrupted download stopped. The file travels directly from TeraBox to your device, so the manager works with the real CDN address. For downloads that stop partway, a download manager is the reliable way to resume without starting over.
how long should a 336 MB TeraBox download take?
In a test on 27 September 2026, a 336 MB file downloaded in 6 m 03 s, with a sustained throughput of 7.4 MB/s. That was the median of 11 runs on mixed 4G and fibre. Your time depends on your connection and the source CDN, so treat it as a reference, not a promise.
what percentage of TeraBox links open overall?
Out of 115 share links across all 8 domains, 94.2% opened during the test on 27 September 2026. The rest failed for reasons like deleted files, password protection, timeouts, or rate limits. That figure is for opening the share, not the download itself.
is there a daily download limit for TeraBox?
Yes. TeraSaver allows 3 anonymous links per day without an account, and 10 per day with a free account. If you reach the limit, the source may return a 429 rate-limit error, which clears on its own after a short wait.
why does my TeraBox download stop at the same point every time?
If the interruption happens at the same point, the cause is specific to that share. In the test, deleted shares made up 29.9% of failed opens and password-protected shares 28.3%. A 504 timeout or a content block could also cut the file. Retrying might not help if the share itself changed.
can a 429 error interrupt a TeraBox download?
Yes. A 429 is a rate-limit response from the source, and it can stop a download if you have made too many requests in a short window. The error clears on its own after a short wait. In the test, rate limits caused 6.3% of failed opens.
does the download go directly from TeraBox to my device?
Yes. The file travels straight from the source CDN to your device and never passes through TeraSaver. The final download address comes from the source, which is why a download manager can use range requests to resume. Your connection and the source's current state decide the actual speed and stability.
